PROBLEM TO BE SOLVED: To provide hollow fiber microporous membranes demonstrating sufficient plasma leakage resistance and stable and excellent gas exchangeability over a long and continuous use, and an oxygenator incorporated therewith. SOLUTION: The hollow fiber microporous membrane is formed of hydrophobic elements with an oxygen gas flux of 10×10<SP>-5</SP>to 500×10<SP>-5</SP>[cm<SP>3</SP>(STP)/cm<SP>2</SP>/sec/cmHg], an ethanol flux of 2-80 [ml/min/m<SP>2</SP>], and communication holes of an average hole radius of 0.008-0.07 μm. The membrane oxygenator incorporated with the hollow fiber microporous membrane has excellent changeability of oxygen with carbon dioxide compared to conventional microporous membranes and membrane oxygenators incorporated therewith, and has plasma leakage resistance allowing a long term continuous use for more than one week.
